Anatomical descriptions of the peripheral part of the lung are varied and inconsistent. They are difficult to relate to bronchographic and radiographic appearances (Twining and Kerley, 1951 Fischer, 1953) or to morbid anatomy. The units in which the periphery has been described may broadly be grouped into two types. The smaller units, measured in millimetres, include those described as the acinus and the primary lobule, and the larger, measured in centimetres, has usually been known as the secondary lobule. To date, attempts to define the secondary lobule have been especially unsatisfactory and, although this paper is concerned primarily with this unit, some preliminary consideration must be given to the smaller units of which it is composed. This smaller unit is concerned with respiratory tissue lying beyond the bronchial tree (Fig. 1), i.e., the alveolar region of the lung.
